Sea slugs or nudibranches as they are more commonly called come in all shapes and sizes. They live in all the world oceans and at varying depths.
The temperate waters of the Pacific Northwest have some very uniquely shaped members and wonderfully photogenic members of the nudibranch family.
This is a White-lined Dirona or Alabaster Nudibranch, Dirona albolineata This white-lined, translucent little slug brillantly appears on drab reefs and rocks like the first snow flakes on winter tundra. Often a clean white, they can vary in colour from cream or greyish-white to salmon pink or purple. These colour variations are due to what these nudibranchs feed on and the colour of that food. Their most distinctive feature is the bright white lines that edge each of their the flattened cerata that project from its back.
Resembling small white flowers these slow moving creatures are wonderful black and white macro subjects when shooting underwater. Providing excellent contrast on the reefs and rocks.
Thanks for reading.
